exidy440.c

0.35b4 [Aaron Giles]


SOUND HARDWARE NOTES:

- The Exidy 440 sound system based on Zonn Moore and Neil Bradley Retrocade CVSD decoder.


WIP:

- 0.113u4: Exidy 440 driver update [Zsolt Vasvari]: Added video timing from schematics. Added the 9 timing PROMs to the ROMsets. All the games appear to use the same timing PROMs with the exception of Top Secret, which sets the VBLANK 4 pixels earlier. This fixes the game graphics, but cuts of the very bottom row of the year display on the title screen. It's most likely a real issue in the game, as tweaking the behavior adds garbage pixels to all the other games.
